This invention relates to new and useful improvements and: structural refinements in devices used for interweaving apatch over a damaged area in fabric material, and the principal object of the invention is to perform the patch weaving 5 operation is-completed, the presence of the patch I cannot be readily detected.

Various different methods have been proposed in the past for installing the patch, but all such methods involve the drawing of the loose threads of the patch through the interwoven threads of,-,20 the material under repair, and since this thread drawing operation is obviously a difficult and. a delicate task, the invisible mending procedure calls for skilled labor and is, therefore, quite expensive. The instant invention seeks to elimihate these disadvantages .byprovidi-ng-an instrument whereby the threaded the patch maybe quickly and easily drawnor inserted through the threads of the material under repair, so that the installation of the patch: may be quickly ande easily effected even by personsof limited skill,

as aforesaid.

The object ofthetinvention is carried out by the provision of an instrument including a'pair of juxtaposed needles which are resiliently con-:

V nected for movement towardandaway fromeach other, so that they are well adapted. to clamp a loose thread of the patch therebetween and to draw or. pass the loose thread through the material under repair. 1

Needless to say, the needles .employed in the instrument are made with utmost precision, and therefore, an important feature 10f the invention resides in the provision of means in the instrument for supporting and manipulating the6'45 needles, this feature eliminating the necessity of machining at substantial expense parts which are large enough to be manipulated by hand.

Another feature of the invention, resides in the structure of the needles themselves, particularly 5 in the structural features of these needles which enable them to firmly and securely grasp or clamp a loose thread of the patch.

Some of the advantages of the invention lie in its simplicity of construction, in its pleasing ape 2 pearanee,v and in its adaptability to economical ma fia i e With the above more important objects and features in view, and such other objects and features as may become apparent as this specification proceeds, the invention consists essentially ofthe arrangement and construction of parts as illustrated the accompanying drawings, in whieh Figure 1 is a perspective view showing the invention inuse; i i

Like characters of reference are employed to designate like parts in the specification and throughoutthe several views.

Referring now to the accompanying drawings in detail, the invention consists of a patch weaving device or instrument designa ed generally by the reference character 2!], the same embodying in its construction agsubstan tially tubular casing L2- having an open end and a closed and i l, the open end of the" casing beingprovided with a tubular adapter ,lfiwhich has a diametrically re- ;duced portion M3 pressed in the open end of the casingasis best shown Figure 2.

The adapter iii is also provided with an outward extension having a tapered outer surface 20, the purpose of which will be hereinafter more fully described. I

What may be referred to as a needle support designated generally by the reference character 22 is positioned in the casing 12 and consists of a pair of juxtaposed arms 24, 26 of resilient material, which are connected together at one end 3 thereof, that is, adjacent the closed end [4 of the casing l2, as indicated at 28.

The free end portions 30, 32 of the respective arms 24, 23 are disposed in the adapter l6 and, by virtue of the resiliency thereof, ar movable toward and away from each other, and a pair of juxtaposed needles 34, 36 are secured by welding, or the like, to the respective arm portions 30, 32, as illustrated in Figure 2.

The needles 34, 35 project outwardly from the adapter 16 of the casing l2 and it is to be noted that the inner end portions of the needles which 1 are secured to the arms 24, 26 are substantially semi-cylindrical in cross-section, as is best shown in Figure 3.

Intermediate portions of the needles, on the other hand, assume the form of shanks having fiat sides 38, 40, respectively, while the respective needles 34, 36 are provided at the outer ends thereof with enlarged heads 42, 44 terminating in pointed extremities 46, 48, respectively.

It is to be noted that the needle 36 is provided in the head end portion thereof with a longitudinally extending channel 50 having a flat bottom 52, this channel being adapted to receive the head end portion of the needle 34 having a flat bottom 54 which i engageable with the flat bottom 52 of the channel when the needle 34 is pressed againstthe needle 36, as indicated by the dotted lines 56 in Figure 2.

Means are provided for pressing the two needles together, these means consisting of a limb 58 which is anchored as at 60 to the side wall of the casing f2 and has an angulated end portion 32 which projects inwardly through registering apertures provided in the casing and in the adapter 16, as indicated at 84. The inner end of the end portion 62 bears against the aforementioned arm 24, and it will be readily apparent that by simply depressing the limb 58 against the casing 12, the arm 24 will be pressed toward the arm 2'5 and the head portions of the needles 34, 36 will be brought together, as aforesaid.

A guide member 66 is pressed in the outer end portion of th adapter 16 and is provided with a slot 68 through which the needles 34, 36 extend, so that the needle 34 is effectively guided in its movement toward and away from the needle 36, as will be clearly apparent.

Finally, it is to be observed that a cap 10, having a tapered open end portion 12, is removably receivable on the tapered outer surface of the adapter 16, so as to protect th needles 34, 36 when the invention is not in use.

The invention is, of course, intended for use in installing a patch '14 on a damaged area 16 in fabric material 18, the patch 14 being of the conventional type and including at its marginal edge a plurality of loose threads 80, as shown in Figure 10.

The invention is intended for pushing the loose threads 80 of the patch 14 through the interwoven threads of the material 18, this being accomplished by simply manipulating the instrument while its needles are separated so that one of the loose threads is disposed in the channel 50 of the needle 33, and thereafter depressing the limb 58 so that the needle 34 is brought toward the needle 36 and the loose thread is tightly clamped between the surfaces 52, 54 of the two needles. The two needles together with the loose thread may then be pushed through the interwoven threads of the fabric 18, after which pressure on the limb 58 is relaxed so that the needles are permitted to spread apart, thus facilitating a release of the loose thread from the needles and permitting the needles to be withdrawn while the loose threads remain extended through the fabric 18. Needless to say, the same procedure is repeated until all the loose threads of the patch '14 are projected through the fabric 18, after which the loose threads are secured by stitching on the reverse side of the fabric to complete the mending operation. If desired, the patch 14 may be basted to the material 18 as indicated at 82 before the mending operation is undertaken, so that the patch does not shift from its proper location while the loose threads thereof are being drawn through th material under repair.

It is believed that the advantages and use of the invention will be clearly apparent from the foregoing disclosure and, accordingly, further description thereof at this point is deemed unnecessary.

While in the foregoing there has been shown and described the preferred embodiment of this invention it is to be understood that minor changes in the details of construction, combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed.

Having described the invention, what is claimed as new is:

In a patch weaving device, a substantially tubular casing, a resilient needle support positioned in said casing and including a pair of juxtaposed arms connected together atone end and having free end portions movable toward and away from each other, a pair of needles secured to the free end portions of the respective arms and projecting outwardly from said casing, said casing having a side wall provided with an opening, and actuating means comprising a depressible limb attached at one end thereof to said casing, the other end of said limb being provided with an angulated portion extending through said opening into the casing and operatively engaging one of said arms whereby said needles may be pressed together to clamp a thread therebetween.
